I'd cringe
And suspect malefide intent on the part of those who wrote that code to show
C# in bad light :-)

Thats partly joke because the java looks somewhat better and C# and Java are
not very different

My main point of course was that between the two extremes:
1. What the language mandates eg python mandates a ':' after the if condition
C mandates that it be parenthesized
2. Matters of free personal taste

there is a large in-between grey area where the language's 'keepers' 
recommend best (and not) practices which may not exactly be the best for a
programmer.

eg Consider perl and python.
As for regex support they are mostly the same
Yet a typical pythonista takes pride that he wrote a 10 line re-free function
where a 2-line re would have sufficed
A typical perl guy will take pleasure in exactly the opposite achievement

A programmer wanting to get his job done need not believe any of these fads&fancies
